In order to solve the above problem, according to one aspect of the present application, the embodiment of the present application provides a laser sight, which includes a housing 1, a laser 2 and an adjusting mechanism 3, with reference to fig. 1 to 9. The housing 1 has a receiving cavity with an opening; the laser 2 is arranged in the accommodating cavity, the laser 2 comprises a tail part 220 and a head part 210 capable of emitting laser, the head part 210 is movably connected with the shell 1, and the laser emitted by the head part 210 can be emitted outwards through the opening; an adjusting mechanism 3 is connected between the tail portion 220 and the housing 1, and the adjusting mechanism 3 is used for adjusting the rotation direction and the rotation angle of the tail portion 220 relative to the head portion 210 so as to change the emitting direction of the laser.

Compared with the prior art, the laser sighting device provided by the embodiment of the invention has the advantages that the head 210 of the laser 2 in the laser sighting device provided by the embodiment of the invention is movably connected with the shell 1, the tail 220 of the laser 2 is adjusted through the adjusting mechanism 3, so that the tail 220 rotates relative to the head 210 to adjust the emitting direction of the laser, and the optical parts in the head 210 are prevented from being damaged when the adjusting mechanism 3 is arranged outside the head 210.

In one embodiment, referring to fig. 1, 3 and 6, the adjusting mechanism 3 includes a first adjusting component 310 and a second adjusting component 320. The first adjusting component 310 is used for adjusting the rotation direction and rotation angle of the tail part 220 relative to the head part 210 along a first radial direction; the second adjusting assembly 320 is used for adjusting the rotation direction and rotation angle of the tail part 220 relative to the head part 210 along a second radial direction; wherein, the first radial and the second radial are arranged in an included angle.

In this way, the tail portion 220 can rotate relative to the head portion 210 along two different radial directions, which effectively increases the adjustment range of the laser.

The spring is used as the elastic member, so that the first elastic member 312 and the second elastic member 322 have the advantages of low price and multiple types and models under the condition of meeting the requirements on the size and elasticity.

It is understood that the first elastic element 312 and the second elastic element 322 may also be spring, rubber or other elastic bodies. The first elastic member 312 and the second elastic member 322 are selected according to actual needs, and are not limited herein.

In another more specific embodiment, referring to fig. 9, the first adjusting member 311 and the second adjusting member 321 are both threaded posts; a thread through hole for screwing the thread column is formed in the shell 1, and the thread column is screwed into the thread through hole and abuts against the outer wall of the tail part 220; the first elastic element 312 and the second elastic element 322 are both springs, and the springs elastically abut between the inner wall of the housing 1 and the outer wall of the tail portion 220; the inner wall of the housing 1 is provided with a first recess 140 for positioning the spring and the outer wall of the tail portion 220 is provided with a second recess 222 for positioning the spring.

Through the arrangement, one ends of the two springs are respectively embedded in the two first grooves 140, and the other ends of the two springs are respectively embedded in the two second grooves 222; the two first grooves 140 are respectively in one-to-one correspondence with the two second grooves 222 and are coaxially arranged. Thus, the first groove 140 and the second groove 222 are matched with each other to guide the spring along the first radial direction and the second radial direction, so that the two ends of the spring are prevented from being deviated when the spring is deformed or is vibrated.

Further, in order to facilitate the installation of the spring by coaxially aligning the first groove 140 and the second groove 222, two positioning grooves 221 communicated with the end surface of the tail portion 220 are disposed on the outer wall of the tail portion 220, and the two positioning grooves 221 are respectively disposed in one-to-one correspondence with the two second grooves 222 of the tail portion 220. Thus, even when the laser 2 is placed in the housing 1, the second recess 222 on the tail portion 220 is covered by the housing 1; the two positioning grooves 221 with notches may also be cut in the end surface of the tail portion 220 to position the two second grooves 222, so that the two second grooves 222 may be aligned with the two first grooves 140 in a one-to-one correspondence and coaxially.
